Tesamorelin (Egrifta SV)

Overview

Tesamorelin is an FDA-approved synthetic GHRH analog designed for HIV-associated lipodystrophy treatment. It provides selective visceral fat targeting with 15-20% visceral fat reduction in clinical trials while preserving subcutaneous fat.

Subcutaneous injection provides optimal bioavailability for GHRH receptor binding and pulsatile GH release stimulation, selectively targeting visceral adipose tissue while sparing subcutaneous fat.

FDA-approved indication showing 15-20% visceral fat reduction in clinical trials.

Unique mechanism that reduces dangerous visceral fat while sparing subcutaneous fat.

Maintained weight loss with continuous treatment over 52+ weeks in clinical studies.

Research areas

• Tesamorelin is an FDA-approved synthetic GHRH analog designed for HIV-associated lipodystrophy treatment. It provides selective visceral fat targeting with 15-20% visceral fat reduction in clinical trials while preserving subcutaneous fat.
• Subcutaneous injection provides optimal bioavailability for GHRH receptor binding and pulsatile GH release stimulation, selectively targeting visceral adipose tissue while sparing subcutaneous fat.
• FDA-approved indication showing 15-20% visceral fat reduction in clinical trials.
• Unique mechanism that reduces dangerous visceral fat while sparing subcutaneous fat.
• Maintained weight loss with continuous treatment over 52+ weeks in clinical studies.

Research notes

• Injection site reactions (17%)
• Development of diabetes or severe glucose intolerance (HbA1c ≥6.5%)
• Severe hypersensitivity reactions
• Excessive IGF-1 elevation (>2 SD above normal) with acromegaly symptoms
• Cognitive improvement isn't a primary effect, but a Phase 2 trial in 152 older adults (55-87 years) showed favorable effects on cognition, particularly executive function (P=0.005), with 117% IGF-1 increases. This suggests potential anti-aging brain benefits, though larger trials are needed for confirmation.

Literature

• Yes, tesamorelin carries a documented 3.3-fold increased diabetes risk compared to placebo. Close glucose monitoring is essential, especially in pre-diabetic patients. Metformin co-treatment may mitigate this risk, and diabetics require careful medication adjustment.

Pharmacokinetics

• Subcutaneous injection provides optimal bioavailability for GHRH receptor binding and pulsatile GH release stimulation, selectively targeting visceral adipose tissue while sparing subcutaneous fat.
